Yep, get every bit of root out as much as humanly possible. Then, if you
still have some babies come up, there's no reason glyphosate (acxtive
ingredient in RoundUp) shouldn't finish the job.

Good luck!

Does anyone have a good solution on how to kill horse radish (wild)
we have some that we cant seem to get rid of, tried digging it up, it
just came up over a wider area, Round-up is not supposed to kill it.
so we are open to suggestions.

Horseradish is supposed to be able to grow back from anything, even the
tiniest fragment of root, So when you dig up growths, DIG them up, don't
pull them up. Be generous in digging around the roots. Eventually it'll
stop
popping up.
